    摘要: An apparatus for reduced-pressure gaseous phase epitaxial growth by suppressing contamination upon the machine parts constituting the rotary mechanical portion and suppressing contamination upon the semiconductor wafer by maintaining the pressure in the rotary mechanical portion to lie within a particular range, and a method of controlling the above apparatus. The apparatus comprises a purging gas introduction pipe 6 for purging the interior of the rotary mechanical portion, a purging gas exhaust pipe 7 for exhausting the gas introduced through the purging gas introduction pipe, a pressure adjusting valve 41 provided in the purging gas exhaust pipe, a pressure gauge 21 for detecting the pressure in the rotary mechanical portion, and an arithmetic/control unit 31 for executing an arithmetic operation based upon the detected pressure and for controlling the opening degree of the pressure adjusting valve 41 provided in the purging gas exhaust pipe, so that the pressure in the rotary mechanical portion assumes a proper value.

    摘要: An improved method of growing a thin film in gaseous phase maintaining a uniform thickness and uniform electric properties such as resistivity, etc. over the whole surface of the film, and an apparatus for growing a thin film in gaseous phase adapted to conducting the above method. A method grows the thin film in gaseous phase by flowing down a film-forming reaction gas through plural gas feed ports 1, 2 formed in the top portion of a cylindrical reactor of an apparatus for glowing a thin film in gaseous phase via flow stabilizer plates 3, and bringing the film-forming reaction gas into contact with the wafer substrate A placed on a rotary susceptor 4 disposed on the lower side thereby to grow a thin film on the surface of the substrate, wherein space formed by the inner wall at the top portion of the reactor B and the flow stabilizer plates 3 is sectionalized into plural spatial sections in a concentric manner with the center of the wafer substrate A as nearly a center point, the gas feed ports 1, 2 are arranged to be corresponded to the sections, and at least either the flow rate or the concentration (8, 9) of the film-forming reaction gas fed to any one of the sections is adjusted.
